Switching assembly used for temperature control of vacuum cup

Abstract

The invention provides a switching assembly for temperature control of a vacuum cup. The switching assembly comprises a water cup (100) and a heat dissipation and heat preservation switching device (300); the water cup (100) comprises a cup body (110); the cup body (110) comprises an outer container (111) and an inner container (112); the heat dissipation and heat preservation switching device (300) comprises a switching mechanism (310) and a sealing piston (320); one end of the sealing piston (320) is located in the area between the cavity wall of the outer container (111) and the outer circle face of the inner container (112), and the other end of the sealing piston (320) is located on the side, facing a rotary cover (130), of a closed end of the inner container (112); the sealing piston(320) and the outer container (111) / inner container (112) are adopted to form sealed sliding guide fit; the area among the sealing piston (320), the cavity wall of the outer container (111) and the outer circle face of the inner container (112) is adopted to form a heat preservation area of the water cup (100), the heat preservation area is of a vacuum structure, and the switching mechanism (310)is used for driving the sealing piston (320) to move in the axial direction of the water cup (100) and further determining whether the water cup (100) is in a heat preservation state or a heat dissipation state.

Description

technical field [0001] The invention relates to the field of living appliances, in particular to a switch assembly for temperature control of a thermos cup. Background technique [0002] With the gradual improvement of human living standards, people are paying more and more attention to healthy drinking water. People gradually develop the habit of drinking hot water, especially in winter. At present, in order to achieve a high heat preservation effect, the thermos cups used on the market do not set through holes on the cups, so as not to reduce the heat preservation effect of the thermos cups, but people usually use thermos cups to hold hot water or hot soup, because thermos cups The heat preservation performance is good and the heat preservation time is long. Therefore, when people need to drink hot water or hot soup in the thermos cup, they often cannot drink it immediately because the temperature of the hot water or hot soup in the cup is too high.

[0002] With the gradual improvement of human living standards, people are paying more and more attention to healthy drinking water. People gradually develop the habit of drinking hot water, especially in winter. At present, in order to achieve a high heat preservation effect, the thermos cups used on the market do not set through holes on the cups, so as not to reduce the heat preservation effect of the thermos cups, but people usually use thermos cups to hold hot water or hot soup, because thermos cups The heat preservation performance is good and the heat preservation time is long. Therefore, when people need to drink hot water or hot soup in the thermos cup, they often cannot drink it immediately because the temperature of the hot water or hot soup in the cup is too high. Pour out the hot boiled water or hot soup at a high temperature and put it in another container or directly remove the cover on the thermos cup, let the hot boiled water or hot soup stand still and reduce its temperature to suitable for drinking, and directly pour the hot boiled water or hot soup Although being exposed to the air is good for cooling down, it is very unhygienic. Larger dust or particles in the air are easy to fall vertically into the cup body and the container of hot boiled water or hot soup, and look for hot boiled water or hot soup again. The hot soup container also brings inconvenience to users. In addition, when people brew instant granule powder drinks, because the instant granule impact drinks need to be stirred, it is very inconvenient to find additional stirring tools such as spoons or chopsticks. For this reason, it is necessary for the present invention to propose a multifunctional water cup, which can stir the liquid in the water cup, and can also carry out heat dissipation and cooling treatment on the liquid in the water cup; during the stirring process, the stirring rod is driven by magnetic coupling Stir the liquid in the water cup, compared with the motor drive method in the prior art, this thermos water cup does not need to open holes at the bottom of the inner tank cavity, and there will be no electric leakage accidents and battery leakage affecting health; heat dissipation and cooling process In the process, the area of ​​the heat preservation area tends to zero and the water cup is switched from the heat preservation state to the heat dissipation state of the ordinary water cup. At the same time, the liquid is stirred by the stirring rod. The combination of the two can quickly dissipate heat and cool down the liquid in the water cup; in addition , The stirring device is equipped with a planetary speed-increasing structure, so the user can rotate the rotating cover at a normal speed to make the stirring rod rotate quickly, that is, the stirring rod can quickly stir the liquid in the water cup; the outer tank of the water cup is equipped with a heat-insulating cover , can prevent people near the water cup from being scalded by accidentally triggering the water cup during the heat dissipation process, and can also assist users to use the water cup to dissipate heat to cover their hands
